Bold, Italics, Strike-through: Won't Go Away!!!!

My Blog at http://www.fvsueetclub.com has lost it's mind! I am using the WordPress WYSIWYG to edit a blog page. And when I click bold, italic, or strike through, everything highlighted becomes bold, italic, or strike-through like it is supposed to. HOWEVER, clicking bold, strike-through, or italic again does not make the style go back to normal. Furthermore, if I look at the code side, there are tags all over the frickin place. It is like a war zone or something. Does anybody have any idea what the heck is wrong with my WordPress blog page editor??????

I tried to put the word strong with the angle bracket things on both sides of the word strong in my post before the words "tags all over" and "war zone" not as a style, but because I was describing my problems with the strong tags. And, as it was supposed to (in this case), but not as I intended, it made the text following the strong tags bold. And now I can't figure out how to edit my post to fix the error. So that is kind of funny. But this problem with my WordPress editor is not funny. I really want to know what the heck is wrong with the WYSIWYG.

I'll publish the page that I'm trying to edit so that you can see the problem which has occured. In addition to the styling problem, I also can't get the editor to move the pictures and the text where I want them to go, so that problem is also apparent on the page.

I recently changed themes from "ChaosTheory" to "Andreas04". I wonder if that could have anything to do with the problem? I read something about themes having the capability to change user preferences behind the scenes, the other day at the http://www.getk2.com site, but I didn't understand what they were talking about.

You described the problem yourself:HOWEVER, clicking bold, strike-through, or italic again does not make the style go back to normal. Furthermore, if I look at the code side, there are tags all over the frickin place.
The visual editor is not MSWord and works a little bit differently: each time you click you add new tags. If you want to undo you have to hit [ctrl]+z (or on a mac [cmd]+z) on your keyboard.
